Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494556, here are decompositions:

17 + 494539 = 494556
37 + 494519 = 494556
59 + 494497 = 494556
113 + 494443 = 494556
149 + 494407 = 494556
173 + 494383 = 494556
197 + 494359 = 494556
229 + 494327 = 494556

Showing the first eight; more decompositions exist.
